| 摘 要： | 钻井液中混有的柴油、改性沥青等含荧光成分的处理剂,给地质钻屑荧光录井分辨带来一定困难。YZ-1型石油荧光分析仪是通过分析原油、柴油和改性沥青的荧光光谱差异而研制成功的。应用该仪器对辛47-28、辛47-35井和冀海1×1探井的岩样进行了荧光分析。结果表明,在没有改性沥青污染的情况下,或改性沥青钻井液的污染低于20mg/L时,YZ-1型石油荧光分析仪可以直接测定钻屑的荧光级別;当污染高于20mg/L时,用荧光强度差减法可以消除钻井液污染造成的那部分荧光干扰;使用YZ-1型石油荧光分析仪的测定结果与地化结果和地质检测结果基本吻合。

| Abstract: | It is difficult to give correct result in fluorologging when some additives containing fluorescent constituent, such as diesel and modified asphalt, existing in drilling fluid. Difference exists between the fluorescence light spectrum of crude oil, diesel, and modified asphalt. Based on this fact, YZ-1 oil fluorescence analyser is developed. Applications in Xin 47-28 well. Xin 47-35 well, and Jihai 1X1 prospecting well indi cate that the fluorescence degree of cuttings can be determined directly by YZ-1 oil fluorescence analyser when the content of modified asphalt in drilling fluid is lower than 20 mg/L or nearly to zero; but above 20 mg/L, the interferences on fluorologging can be over-comed by minusing modified asphalt fluorescence intensity. It is shown that testing result of YZ-1 oil fluorescence analyser is accordance with geological testing result. |
